Maximum clade credibility tree obtained from a BEAST analysis of the combined Euphorbia GDD dataset, showing the distribution of the 67 samples selected for trait analyses, from a total of 279 samples. Black branches indicate parts of the larger phylogeny captured by our subsample (i.e., taxa for which multiple samples were available and whose monophyly was confirmed). Stars indicate the location of those 67 samples. Grey branches indicate parts of the larger phylogeny not captured by this subsample. The seven subclades emphasized in the text are labeled
